The UK Government has updated its guidance on managing rainwater in new developments – good news for people, wildlife, and green spaces. These standards also offer helpful advice for retrofitting existing homes, streets, and public spaces to be more climate-resilient by using rainwater as a resource.
So, what’s changing?
Rainwater harvesting is now the top priority. Many already use water butts, but retrofits should also consider storage tanks, greywater systems, rain gardens, green roofs, and ponds to manage rain naturally rather than sending it straight to sewers.
The new rules encourage collecting and reusing rainwater to reduce surface runoff, add greenery, and support biodiversity. Retrofitting options include permeable driveways and bioswales in homes, car parks, and streets, helping to create green infrastructure in our communities.
Nature-friendly design: Include some of these features to support birds, bees, and other wildlife.
Better spaces for people: SuDS can also serve as attractive community areas, such as planted walkways, play-friendly spaces, or wetlands.
Plan for the long haul: Drainage systems need clear maintenance plans to ensure they remain effective and safe over time.
Well-designed SuDS reduce flooding, improve drought resilience, clean rivers, and create greener, healthier spaces for all. These new standards ensure our future homes work with nature, not against it.
